MACHINE FOR AGITATING LIQUIDS.

SPECIFICATION forming part of Letters Patent No. 392,987, dated November 20, 1888.

Application filed June 23, 1888. Serial No. 278,064. (No nodelJ To aZZ whom it may concern:

Be it known that I, HENRY CARPENTER, a citizen of the United States, residing at Davenport,in the county of Scott and State of Iowa, have invented a new and useful Machine for Agitating Liquids, of which the following is a specification.

My invention relates to that class of machines in which liquids in vessels are agitated by rapidly-reciprocating movements; and the objects of my improvements are, first, to expeditiously press the covers over the mouths of the vessels preparatory to agitating the fluid; second, to expeditiously secure the covers in position when so pressed over the mouths of vessels, and, third, to expeditiously remove the pressure of such covers over the mouths of the vessels when the fluid has been sufficiently agitated preparatory to removing such vessels from the machine. I accomplish these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a front view of a machine for agitating liquids. Fig. 2 is aside View of the same, the drive-belt wheel and vessel-carrier removed. Fig. 3 is a front View of the top of the plunger-rod, cross-head, and handle. Fig. 4 is a top view of the cross-head, and Fig. 5 is a bottom View of the handle.

Similar letters refer to similar parts throughout the several views.

In carrying outv my invention I employ a suitable frame, preferably containing the three standards 1 2 3, diverging from the trunk A and attached to the floor-rim 4:. A cross-bar, 5, extends from standards 1 and 2,attached to the same. A shaft, (1, is journaled through cross-bar 5 and into bracket 1), which bracket is attached to said crossbar by bolts at 6 and 7. On the shaft'c, between cross-bar 5 and bracket Z), is rigidly attached belt-pulley wheel a, and on the opposite side of cross-bar 5 is attached rigidly to shaft a crank-wheel d. Pitman e is attached to crank-wheel (Z by crank-pin f, the upper end of said pitman being pivoted to plunger-rod B at g. Plunger-rod B passes through bearing h at the upper end of standard 3 and the bearingj on the back of trunk A. On plunger-rod 13, above trunk A, is attached the vessel-carrier z, consisting of two or more laterally-extending arms, at the end of each of which are the cups 7a for supporting a tumbler, J. Plunger-rod B extends above the vessel-carrier a suitable distance,and near its upper end is a longitudinal slot, Z.

Gross-head O has a cylindrical body, D, perforated longitudinally to accommodate plunger-rod B with two or more laterallyextendiug arms, E E. The upper end of said body D is notched, as shown at m and m the vertical part of said notches extending obliquely, as shown at n and n The lower portion of said body D has a perforation threaded to accommodate the screw 0, which enters into slot Z upon plunger-rod B.

The handle F has a body, G, perforated longitudinally to accommodate plunger-rod B,

and has two laterally-extending arms, H H.

The lower endof said. body G is notched, as shown at'p p, the outer surfaces of the vertical part of said notches extending in a tangent, as shown at q q. Beneath the body D of cross-head O the spiral spring I encircles plunger-rod B, and is supported upon. pins 1" r in said plungerrod. The top or upper end of plunger-rod B terminates in cap 8, which prevents the handle F from becoming disengaged from said plunger-rod.

The rotation of handle F on plunger rod 13 causes cross-head O to move downward on said plunger-rod by cam movement, and the screw 0, guided in the slot Z, prevents rotation of cross-head G, and its downward movement on said plunger-rod compresses spiral spring I against the supports 1 r. In the rotation of handle F its tangentially-constructed parts q g come in contact with the oblique parts nn? of cross-head O, preventing further rotation of handle F and locking or securing the same in position. In the reverse rotation of handle F spiral spring I exerts a force against the'bottom of cross-head O, and thus against handle F,to force these parts upward against cap 8.

Tumblers J are placed in the cups 7c and caps K placed over the mouths of said tumblers,and the extreme ends of the arms H,bearing against the tops of said caps K, are by the means indicated pressed and held over the mouths of saidtumblers during the operation of agitating the fluid therein, and after such agitation ceases are removed by the means just indicated.

On the upper part of trunk A is the main driving-pulley belt-wheel L on the shaft t attached to said trunk, and extending around said wheel L and wheel 0 is the continuous belt a. Wheel L is provided with the handle 1;.

The operator rotating wheel L causes the rotation of Wheel 0, shaft a, crank-wheel d, which, through pitman 0, causes an upward and downward movement to plunger-rod B and its attachments.

' I do not claim, broadly, a device for lowering a cross-head to secure the caps over the mouths of the tumblers or for raising the crosshead for releasing the same, because such device is old; but I claim my peculiar device, consisting of the structures stated for forming the combinations to produce the results; and

Therefore what I claim as new, and desire to secure by Letters Patent, is-

1. In a machine for agitating liquids, the combination, with the plunger-rod B, provided with the supports r r, of the cross-head 0, having a cylindrical body, said body having tangential notches or bevels, and the handle F, having the body G, with like bevels which register with the bevels of the crosshead, and spring I, interposed between the bottom of the body of said cross-head and said supports 1" r of the plunger-rod, substantially as described.

2. In a machine for agitating liquids, the combinatiomwith the plunger-rod B, provided with supports 0' 1' and slot Z, of the cross-head 0, having a cylindrical body, said body having tangential notches or bevels, and a screw, 0, arranged to enter and slidein slot Z, and the handle F,having the body G,with like bevels, which register with the bevels of the crosshead, and spring I, interposed between the bottom of the body of said cross-head and supports M of said plunger-rod, substantially as described.
